A Gwinnett County man turned himself into authorities Friday after allegedly stabbing his manager in the neck upon being fired from his job at a Duluth restaurant.

Gwinnett County Master Police Officer Collin Flynn said 44-year-old Kesely Ingram is facing charges of Aggravated Assault and Aggravated Battery in connection with the incident at the On The Border Mexican Grill and Cantina on Pleasant Hill Road. Police say they responded to the restaurant to find the manager with "severe wounds". The manager's name has not been released.

Employees who saw the incident told police that the attack happened when the manager fired Ingram.

"During the process of firing him, the employee stood up, walked over to his boss and began stabbing him with some type of sharp object," Flynn said.

Ingram, who had been an employee of the restaurant for around 10 years, allegedly fled the scene but later turned himself in to detectives at the Gwinnett County Police Department's Central Precinct. Flynn said he was taken to a hospital for minor injuries he suffered during the attack and was eventually booked into the Gwinnett County Jail.

The manager remains hospitalized in serious condition, but Flynn said his injuries are not considered life-threatening.

Gwinnett officials are still investigating the incident and some details have still not been released, including what sharp object was used in the attack.
